Lunar pits could shelter astronauts, reveal details of how 'man in the moon' formed

Posted: 17 Jul 2014 03:04 PM PDT

While the moon's surface is battered by millions of craters, it also has over 200 holes -- steep-walled pits that in some cases might lead to caves that future astronauts could explore and use for shelter, according to new observations.

Cheap, highly efficient solar cells: A new stable and cost-cutting type of perovskite solar cell

Posted: 17 Jul 2014 12:15 PM PDT

Scientists have made a very efficient perovskite solar cell that does not require a hole-conducting layer. The novel photovoltaic achieved energy conversion efficiency of 12.8 percent and was stable for over 1000 hours under full sunlight. The innovation is expected to significantly reduce the cost of these promising solar cells.

Scientists experimentally re-create conditions deep inside giant planets, such as Jupiter and many exo-planets

Posted: 17 Jul 2014 11:20 AM PDT

Using the largest laser in the world, scientists for the first time have experimentally re-created the conditions that exist deep inside giant planets, such as Jupiter, Uranus and many of the planets recently discovered outside our solar system.

When is a molecule a molecule? Scientists watch fast electron jumps in exploding molecules

Posted: 17 Jul 2014 11:20 AM PDT

Using ultra-short X-ray flashes, an international team of researchers watched electrons jumping between the fragments of exploding molecules. The study reveals up to what distance charge transfer between the molecular fragments can occur, marking the limit of the molecular regime. Such mechanisms play a role in numerous chemical processes, including photosynthesis.

Earth-like soils on Mars? Ancient fossilized soils potentially found deep inside impact crater suggest microbial life

Posted: 17 Jul 2014 09:50 AM PDT

Soil deep in a crater dating to some 3.7 billion years ago contains evidence that Mars was once much warmer and wetter, says a geologist based on images and data captured by the rover Curiosity.

Is the universe a bubble? Let's check: Making the multiverse hypothesis testable

Posted: 17 Jul 2014 09:48 AM PDT

Scientists are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science. Never mind the Big Bang; in the beginning was the vacuum. The vacuum simmered with energy (variously called dark energy, vacuum energy, the inflation field, or the Higgs field). Like water in a pot, this high energy began to evaporate -- bubbles formed.

Potential new therapy with brain-on-a-chip axonal strain injury model

Posted: 17 Jul 2014 08:49 AM PDT

The use of 'Brain-on-a-Chip' microsystem has been used to assess specific effects of traumatic axonal injury. This innovative approach was used to characterize the biochemical changes that are induced following traumatic axonal injury and highlights an apparent injury threshold that exists in axonal mitochondria.

Anti-tank missile detector joins fight against malaria

Posted: 17 Jul 2014 06:51 AM PDT

State-of-the-art military hardware could soon fight malaria, one of the most deadly diseases on the planet. Researchers have used an anti-tank Javelin missile detector, more commonly used in warfare to detect the enemy, in a new test to rapidly identify malaria parasites in blood. The technique is based on Fourier Transform Infrared (FITR) spectroscopy, which provides information on how molecules vibrate.

Birdsongs automatically decoded by computer scientists

Scientists have found a successful way of identifying bird sounds from large audio collections, which could be useful for expert and amateur bird-watchers alike.

Math can make the Internet 5-10 times faster

Posted: 17 Jul 2014 06:48 AM PDT

Mathematical equations can make Internet communication via computer, mobile phone or satellite many times faster and more secure than today. A new study uses a four minute long mobile video as an example. The method used by the Danish and US researchers in the study resulted in the video being downloaded five times faster than state of the art technology. The video also streamed without interruptions. In comparison, the original video got stuck 13 times along the way.

Development of automatic system for translating biomedical patents in real time

Posted: 16 Jul 2014 06:07 AM PDT

A prototype of an automatic translation system for patents in the biomedical area has been developed by researchers. The system can be used to create multilingual documents with the same structure as the original patents, including images, formulae and other kinds of annotations. In addition, the system works in real time and can be incorporated in web applications.

Telecare intervention improves chronic pain, study shows

Posted: 15 Jul 2014 01:58 PM PDT

A telephone-delivered intervention, which included automated symptom monitoring, produced clinically meaningful improvements in chronic musculoskeletal pain compared to usual care, according to a study. Pain is the most common symptom reported both in the general population and patients seen in primary care, the leading cause of work disability, and a condition that costs the United States more than $600 billion each year in health care and lost productivity. Musculoskeletal pain accounts for nearly 70 million outpatient visits annually in the United States each year. Telemedicine strategies for pain care have been proposed but not rigorously tested to date.
